In using the jack as a rim tool, a pair of similar members 26 are used for engaging diverse points on the rim at the side of said rim opposite to the point engaged by the hook portion 23.

The members or arms 26, as shown in F ig-' ure 4, are each provided at one end with a transverse journal portion 27, and at the other end with a shoe 28 similar to the shoe 22. Each member 26 consists essentially of the journal portion 27, the shoe 28 and the longitudinal supporting converging elements or members 29 which join the journal- 27 at either end of the latter and connect the same to said shoe. A plurality of transverse supporting members 30 are also provided longitudinally spaced between the elemerits-29.

In each member 26 there is provided inwardly of the journal 27, a transverse groove 31 or restricted portion extending across one of the elements 29. The purpose of the groove 31 is to permit the journal 27to enter any one of the bearing sockets 4 or 5 when at a given angular position and aligned with said socket.

In the operation of removing a rim from the tire, the pair of members 26, as shown in Figure 1, are engaged in either the bearing sockets 4 or 5, depending upon whether a rim of smaller or larger diameter is to be removed from its tire, and the shoes 28 are hooked over the edge of the rim. The shoe 7 22 on the bolt 8 is run out of the jack by turning the cylindrical member 16 sufliciently to enable the latter shoe to hook over the side of the rim opposite to that engaged by the shoes 28.

The shoe 22 is preferably hooked over the rim near'one of its ends. The jack crank is then'inserted in the cylindrical member 16 for rotating the latter and drawing the shoe 22 downwardly, removing the rim from the tire. j

When the jack is used for lifting purposes it is desirable that means be provided so thatsaid jack may be positioned underneath without necessitating the person using the jack getting under the car or other object to be lifted in. any inconvenient position. To accomplish this, there is provided a collapsible extension 32 having legs 33 and 34 connected together by a hinge clip 35. The clip 35 is formed into a channel for receiving the ends of the legs 33 and 34. The leg 33 is held rigidly in the clip 35 against the bottom of the latter by means of a rivet or pin 36. The leg 34 is bent slightly at the end thereof, the bent portion being hinged in the clip 35 by means of a pin 37. The sides of the clip 35 below the pin 37 are formed to extend inwardly as indicated in Figure 10 to resiliently lock the leg 34 when the latter is in the bottom of the clip 35 and in alignment with the leg 33.

The crank handle 38 for the jack, Figure 8, is provided with-diametrically positioned, outwardly extending lugs 39 which are adapted to enter into the bayonet slots 19 of the cylindrical member 16' and lock said handle therein upon a slight rotation of said handle. The upper .end of the leg 33 is provided with lugs 40, similar to the lugs 39. The lower end of the leg 34 has pinned thereto a collar, the collar 41 being apertured to receive the crank 38 and provided on its inner periphery with bayonet slots 42 similar to slots 19 for receiving and locking the lugs 39 on said crank.

Jacks for automotive vehicles are usually stored when not in use in a manner which would make it inconvenient for them to have a very'large base. In the case of automobiles, the jacks are frequently stored under the seat and consequently it would be very advantageous to have a removable base. For this reason there is provided a large rectangular base plate 43 which is provided with a pair of upwardly extending longitudinally spaced lugs 44 on the upper side thereof adapted to fit on either side of one of the ears 3. A pair of inwardly and upwardly extending lugs 45 are formed on the upper side of plate 43 and are positioned opposite to the lugs 44, a' distance substantially equal to the width of the bottom of the sleeve 1. Between the upper ends of the lugs 45 is provided a journal 46 which is adapted to enter one of the bearing sockets 5 One of the lugs 45 is provided with a restricted portion (not shown) simi lar to the groove 31 to permit the journal 46 to enter one of the bearing sockets 5 when the sleeve 1 is held ina definite angular position with respect to the base plate 43. After the journal 46 entersone ofthe bearing sockets 5 the sleeve 1 may be pivoted about the journal 46 to bring the bottom of said sleeve against the upper side of the base plate 43, the ear 3 opposite to said ournal entering between the lugs 44. I

i The operation of the device simply as a I jack is obvious. The operation of the device as a rim tool has been explained above. It will be apparent that the use of the above described device will enable many who have previously found it very inconvenient to re move and replace rims from. tires to do so with very little trouble. v r

It will also be obvious that a great conven-- ience is accomplished by providing a com 5 bined rim tool and jack, the function of a rim tooland a jack both being required'in the actual removal of a rim from the tire.

I am aware that many changes may be made and numerous details of construction may be varied through a wide range With- 1 out departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art. 15 I claim as my invention: I
